QUICK ATTACHABLE BUTTON Filed Aug. 14, 1967 INVENTOR.

HARRY POMERAN TZ United States Patent US. Cl. 24-108 3 Claims ABSTRACT OF THE DISCLOSURE A button provided with means for quickly securing the button to cloth, leather, fabric, as earrings, tie clasps or other material without the use of thread and for as quickly releasing said button as desired.

Summary of the invention My button has a central circular hole. I provide a hollow cylinder having an enlarged closed head at one end, the other being open. The cylinder extends through the button hole with the head contacting the front or exposed surface of the button. Releasable prong securing means is disposed within the interior of the cylinder adjacent the other end. An elongated prong pointed at one end and having a transverse disc of diameter larger than the other end of the cylinder at its other end extends through the material to which the button is to be secured into the securing means until the material is held tightly between the other end of the cylinder and the disc. The prong and securing means can be engaged or disengaged by manual operation of the user quickly and easily whenever necessary.

Detailed description of preferred embodiment Referring now to FIGS. 1-9, there is shown a button 10 having an enlarged central circular hole through which hollow cylinder 22 extends housed in sleeve 12. One end of the cylinder 22 has a threaded bore receiving a bolt 14 terminating into an enlarged head 16 bearing against the exterior surface of the button. The end of the bolt extending into the hollow cylinder has a central recess 18. Cylinder 22 has, intermediate the ends and somewhat spaced from the recess, two oppositely disposed L shaped slots 20 in the wall thereof. The opposite end of cylinder 22 has a reduced opening 24 which tapers outwardly as it communicates with the cylinder interior chamber 27.

A hollow truncated cone 26 has its smaller, open end 3,440,692 Patented Apr. 29, 1969 ice 28 extending into opening 24. The larger end 30 has an upstanding prong 32 alignable with recess 18. A -coil spring 34 encircles prong 32. One end of the spring bears against the bolt 14; the other end of the spring bears against end 30. The axis of the cone is aligned with the axis of the cylinder. The cone is rotatable about its axis. Cone 26 adjacent its larger end has a shoulder 36 provided with two oppositely disposed pins 38, each of which is engageable with a corresponding one of the L shaped slots 20. Cone 26 further has three spaced apart slots 40 which extend from the smaller end upwards toward the pins 38. The top ends of these slots are enlarged circles 42.

A prong 44 of generally torpedo shape has a point 46 at one end and a transverse generally hexagonal or circular disc 48, larger in diameter than end 22, at its other end. This prong adjacent disc 48 has a region reduced in cross section with three flat sides 50 having corners 51 to define a three sided polygon with the shape of an equilateral triangle. The prong otherwise has a cross section which is circular although variable in diameter.

In use, prong 44 is moved with point 46 extending through the material 54 to which the button is to be 'secured into opening 24; the prong is pushed in until the slots have engaged the tips 51 of triangle 52 which enables the cone to be rotated, and spring 34 passes downward on the cone to lock the prong into the cylinder.

To release the prong, it is pushed in and rotated clockwise until the pins 38 engage the horizontal portions of slots 20 to lock the cone in raised position and restrain the spring from forcing the cone downward. The prong can then be pulled out of the cylinder to release the button from the material.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In combination with a button having a circular hole, a hollow cylinder having an enlarged closed head at one end and open at the other end, said cylinder extending through said hole with said head contacting the front surface of the button, a hollow truncated cone constituting releasable prong securing means and disposed in said cylinder, the axes of said cone and cylinder being coincident, the cone being open at its smaller end, the other end of the cylinder having a tapered orifice accommodating with a flush fit the smaller end of said cone, and an elongated prong having a point at one end and a transversely extending disc of larger diameter than the other end of said cylinder at the other prong end, said prong extending through the other end of the cylinder to a depth at which said disc is adjacent said other cylinder end.

2. The combination as set forth in claim 1 wherein the larger end of said cone is spring loaded and is normally biased toward the other end of the cylinder and wherein said cone is provided with a plurality of spaced apart generally axial slots extending from a point intermediate its ends to its smaller end.

3. The combination as set forth in claim 2 wherein said cylinder is provided with two oppositely disposed L shaped slots and said cone is provided on its outer surface adjacent its larger end with two oppositely disposed pins, each pin engaging a corresponding cylinder slot.
